In this chapter, we looked at how to use Docker Machine to create the Docker hosts locally on VirtualBox and reviewed the commands you can use to both interact with and manage your Docker Machine-launched Docker hosts.
We then looked at how to use Docker Machine to deploy Docker hosts to your cloud environments, namely DigitalOcean. Finally, we took a very quick look at how to launch a different container-optimized Linux operating system, which was CoreOS.
I am sure you will agree that using Docker Machine made running these tasks, which typically have very different approaches, a very consistent experience, and which, in the long run, will save a lot of time as well as explaining.
In the next chapter, we are going to move away from interacting with single Docker hosts to launching and running a Docker Swarm cluster.
